Batman v Superman: Dawn of Justice director Zack Snyder has posted a new picture of lead actor Ben Affleck on Twitter, showing a battle weary Caped Crusader with stubble and dusty mask.

Snyder posted the image in honour of the 75th anniversary of the Batman franchise.

It forms part of a photo montage DC created for Comic-Con, with the company noting on its blog: "Yes, as fans have started pointing out, within the dozens of photos and illustrations on the wall is a brand new image of Batman from the upcoming film ‘Batman v Superman: Dawn of Justice.

"The filmmakers wanted to include this new cinematic version of the Dark Knight in the anniversary mosaic so it could be discovered by fans.”
